VE NDING-MACHINE.

Specification of Letters Patent.

Patented Sept. 8, 1908.

Application filed September 6, 1905. Serial No. 277 ,220.

T 0 all whom it may concern:

Be it known that I, ALEXANDER JA'EGER, a citizen of the United States,residing in Philadel hia, Pennsylvania, have invented certain Improvements in Vending-Machines, of which the following is aspecification.

My invention relates to coin actuated vending apparatus of the typeshown and described in the patent of Otto Jaeger, dated August 2, 1904,and numbered 766,445.

The object of my invention is to facilitate the discharge of thearticles to be vended and to provide a construction-that will take careof vendible units whose general dimensions are the same, but which mayvary in size a slight degree and hence are not readily vende'd instructures wherein the feeding, discharge and actuating mechanisms arebased upon certain proportional dimensions.

My invention is fully shown in the accompanying drawing, in which:

Figure 1, is a sectional elevation of the vending structure made inaccordance with my invention, showing it in the inactive position; Fig.2, is a similar view, showing the apparatus in position to eject thevendible units Fig. 3, IS a front elevation of the carrier for thevendible units, and Fig. 4, is a modification of the coin actuating orcontrolling means.

The general form of vending apparatus to which my improvements have beenapplied is shown in the patent above referred to, and hence it will beunnecessary to describe the same at len th herein.

The artic es 1, to be vended, are carried by a platform 2 suspended bybands or cords 3 depending from wheels or drums 4 on a shaft 5, whichshaft is carried at thetop of a suit able frame 6. The sides of theframe are slotted at 7 for the passage of end projections 8 of theplatform 2, to which projections said bands 3 are connected. The shaft 5carries a coiled band spring 9 which is wound by the depression of theplatform 2, said spring havmg a constant tendency to raise saidplatform.

Journaled in the frame 6 and disposed below the shaft 5 is a shaft 10carrying a pair of escapement wheels 11 held against turning by means ofa pawl 12; the upper vendible unit being in engagement with saidescapement wheels. The pawl 12 is mounted on a rock-shaft l3 and isprovided with an extenment wheels moving more than one tooth or aquarter revolution at a time.

A coin chute 15 is provided, having the usual means for ejecting improor 001118 or slugs, and the lower end of this 0 ute is beveled at 17.Extending from the shaft 13 is an arm 18 having an angular portion 19lying against the beveled lower end of the coin chute and held in suchposition by means of a spring 20. Upon passing a coin into said chute itdrops to the lower end, and in leaving the chute it pushes theprojection 19 out of the way. This causes the pawl 12 to release theratchet wheel, whereupon the sprin 9, whose constant tendency is toraise the p atform 2 carrying the vendible units, exerts its force andcauses the upper vendible unit to press against the rounded back of theteeth of the escapement wheels in engagement with said units, causingsuch In loading'the machine, the articles are placed successively on theplatform 2, which is de ressed to permit such action and in order t atit may be satisfactorily held during such loading, I provide the shaft 4with a ratchet wheel 25 engaged by a pawl 26 which is weighted so as tonormally hold said shaft against movement during this operation. Thispawl has a lower extension 27 pivoted at 28, with a side projection 29,and when the machine has been filled, the uppermost unit is in positionto engage this projection and keep the pawl 26 away from its ratchetwheel 25 and thereby permit the successive ejectment of the vendibleunits. The extension 27 is guided by a pin 30 exterding into the slot 7.

Fig. 4, illustrates a modified form of coin chute 15 and escapementmechanism. The

rock-shaft 13 carries a pawl 12 having an extension 14, and a spring 20'coiled around said rock-shaft serves to keep the awl in the properengagmg position. A p atform 31 pivoted at 32 is provided to recelve thecoin,

sion 14 which serves to prevent the escape- 55 pawl 12 and the balanceof the vendi- 80 and a rod 32 connects said platform with the rock-shaftso that the latter may be turned by the dropping of the coin on saldplatform.

In my improved construction no part of the apparatus de ends upon thepro ortional dimensions the articles to be ven' ed,

- inasmuch as the operation of the mechanism,

vtooth of the after it has been released or actuated by a coin,depends'simply upon the force exerted by the coiled spring, which tendsto raise the vendible units against the escapementwheels.

Havin thus described my invention, I claim an desire to secure byLetters Patent:

1. The combination, in a vending a paratus, of a frame or guide, alatform 'or the articles to be vended, a sha t, drums at the end of saidshaft, bands arranged to. .be wound on said drums and attached at theiropposite ends to said platform, a coiled s ring on said shaft forturning the same to hftthe platform, said spring being wound when theplatform is depressed for the reception 0 the vendible units, escapementmeans comprising a toothed wheel and a pawl normall in enga ementtherewith for co-action wlth said 1' ting means, said a pawl therefor,and an arm carried by the pawl for controllin said ratchet, said armying in the ath o the vendible units and engaged by t e same so as tohold .the said pawl out of engagement. r

2. In a vending apparatus, the combination of a platform for thevendible units, a

shaft from which said platform is'sus ended,

means tending to raise said lat or'm, a ratchet Wheel carried bysaidshaf t, apawl for engagement with said.ratchet wheel, and an extensioncarried by said pawl and lying in the path of, the vendible unitswhereby the engagement of said extension by the vendi-' ble units holdsthe pawl normally out of engagement with the ratchet wheel.

3. In a vending apparatus, the combination of a platform for thevendible'units, a shaft from which said platform is suspended, a torsionspring. carried by said shaft and tending to raise said platform, aratchet wheel carried by said s aft, a awl for engagement with saidratchet whee and an ex- I tension carried by said pawl and lying in thepath of the vendible units whereby the engagement of said extension bythe vendible units holds the. pawl normally out of enga ement with theratchet wheel.

n testimony whereof, I have signed my name to this specification, in thepresence of two subscribing witnesses.
